Noticed pies cooked by journalist (6)
I believe the answer is:
espied
'noticed' is the definition.
(I've seen this in another clue)
'pies cooked by journalist' is the wordplay.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'by' says to put letters next to each other.
'journalist' becomes 'ed' (short for editor).
'pies' anagrammed gives 'espi'.
'espi'+'ed'='ESPIED'
(Other definitions for espied that I've seen before include "observed in literature" , "Spotted; saw" , "Glimpsed" , "Saw (archaic)" , "Caught sight of (archaic)" .)
